AUTOMATIC TRAIN-PIPECOUPLING.

SPECIFICATION forming part of Letters Patent N o. 619,401, datedFebruary 14, 1899.

Application tiled October 17, 1898. Serial No. 693,764. (No model.)

To all whom it may concern/.-

Be it known that I, JOSEPH E. FoEsYTH, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Automatic Train-Pipe Couplings,of which the following is a specification.

My present invention is primarily designed to aiford an improvement onthe automatic train-pipe coupling set forth in my application, SerialNo. 681,883, iiled May 27, 1898; and it relates to a simplification ofthe construction of the section in the train-pipe behind the couplingrendered telescopically yielding to permit the coupling, which isattached to the draw-bar, to follow the reciprocatory movements of thedraw-bar under the influence of its spring.

Referring to the accompanying drawings, Figure l is a longitudinalbroken section of a car with the train-pipe upon it for air, steam, orwater and the coupling both shown in elevation and connected together bymy improved device for the purpose; Fig. 2, a section taken at the line2 on Fig. 1 and viewed in the direction of the arrow; Fig. 3, a sectiontaken at the line 3 on Fig. l and viewed in the direction of the arrow;and Fig. 4, a section taken at the line 4 on Fig. 1 and viewed in thedirection of the arrow.

A denotes the bottom of a car carrying the sills, one of which ispresented at B, between which the draw-bar C, terminating in thedraw-head C', is confined in the usual or any suitable manner.

E is the coupling for the train-pipe D, (airpipe, steam-pipe, orwater-pipe.)

The coupling illustrated, which is suspended from the draw-bar anddraw-head, as shown, involves the construction set forth in my aforesaidformer application, lbut may be of any other construction suitable foruse with it of my present improvement,which relates to means forconnecting the coupling iiexibly with the pipe D. This pipe extendsalong the outer side of a sill B, being supported in hangers r r on thecar-bottom, and the hanger fr near each end of the pipe on a car is ofthe loop shape shown in Fig. 4 to allow the end portions to yield invertical direction Within the limits of their springy quality, for apurpose hereinafter explained.

At each end of the pipe D it is connected with the coupler E, as shownof the end presented to view in Fig. l, by means of my improvedconnecting means F, involving as its preferred construction thefollowing: A socket 1o projects at a right angle from the end of thepipe D, which may be extended nearly to the end of the car. A plug o,preferably tapering, as shown, extends from one end of an elbow n,fastened at its opposite end to one extremity of a pipe-section m, theconnection being that of a swing-joint to permit this pipe-section toturn or swing freely back and forth on the socket p. At the oppositeextremity of the pipe-section m it carries a similar elbow n',terminating in a plug o', like the plug o, and fitting, like the latter,in a socket p', extending at a right angle from the rear end of thecoupling E.

The connection F requires, of course, to be of suflcient length to reachfrom the plane of the pipe D (indicated at the dotted line a: in Fig. 3)to that of the coupler E, (indicated at in the same figura) and it thusoccupies the oblique position in which it is shown, though it isquite'feasible to cause it to depend perpendicularly toward the couplerfrom a rightangled extension of the pipe D, a construction which is tooobvious to require illustration.

As will be seen, the device F affords a comparatively inexpensive andvery simple and easily-applicable flexible connecting medium between thetrain-pipe and the coupling, which yields to permit the coupling toyield correspondingly with the draw-bar under the reciprocatorymovements to which it is subjected in use. Strain upon the connectionand the coupler, which would ensue were the pipe D unyielding toward itsend portion by the arc the lower end of the pipe-section m would thenhave to describe in being swung by the movements of the draw-bar behindand ahead of a perpendicular line from the end of the train-pipe, isavoided by the loose support r to the end portion of the pipe, wherebyit may yield from its normal horizontal position under the swingingmovements of the connection F. As will also be seen, my improvedconnecting device eec- IOO tually supplants the more cumbersome andexpensive telescoping connection shown in my aforesaid application.

While the particular construction shown and described of my improvedconnecting device is believed to be the best for its purpose, I do notlimit my invention thereto, since without departure from it the deviceand the manner of its connection may be variously modified by thoseskilled in the art.

What I claim as new, and desire to secure by Letters Patent, is-

l. In combination With a car, a train-pipe and an automatic couplingtherefor suspended on the draw-bar, and a metal pipe-section extendingobliquely from said pipe to said coupling and connecting them flexiblytogether, substantially as and for the purpose set forth. l

2. In combination with a car, a train-pipe and an automatic couplingtherefor sus-V pended on the draw-bar, and a pipe-section extendingobliquely between and having swing-joint connections at its oppositeends .respectively with said train-pipe and coupling, substantially asand for the purpose set forth.

3. In combination with a car, a train-pipe D terminating in a socketp,and an automatic coupling E therefor suspended on the drawbar and havinga socket p at its rear end, and a pipe-section fm, terminating at itsopposite ends in plugs o and o' rotatably confined, respectively, in thesockets 1J and p to connect said coupling yieldingly with saidtrain-pipe, substantially as described.
